Similar to the B-tree, the R-tree is also a balanced search tree (so all leaf nodes are at the same depth), organizes the data in pages, and is designed for storage on disk (as used in databases). Each page can contain a maximum number of entries, often denoted as M {\displaystyle M} .
The total insert complexity is still comparable to the R-tree: reinsertions affect at most one branch of the tree and thus () reinsertions, comparable to performing a split on a regular R-tree. So, on overall, the complexity of the R*-tree is the same as that of a regular R-tree.
Hilbert R-tree, an R-tree variant, is an index for multidimensional objects such as lines, regions, 3-D objects, or high-dimensional feature-based parametric objects. It can be thought of as an extension to B+-tree for multidimensional objects.

An R+ tree is a method for looking up data using a location, often (x, y) coordinates, and often for locations on the surface of the Earth. Searching on one number is a solved problem; searching on two or more, and asking for locations that are nearby in both x and y directions, requires craftier algorithms.
When r ≥ 4 is a power of 2, then the radix trie is an r-ary trie, which lessens the depth of the radix trie at the expense of potential sparseness. As an optimization, edge labels can be stored in constant size by using two pointers to a string (for the first and last elements).

A triangle in a real tree. A metric space is a real tree if it is a geodesic space where every triangle is a tripod. That is, for every three points ,, there exists a point = such that the geodesic segments [,], [,] intersect in the segment [,] and also [,].
